Landing advice

One of the methods I used, was to watch the auto pilot at work during the landing and simply copy it. Remember that mathematics plays a big part in flying and computers. The aircraft normally approaches at a 2.5 to 3 degree nose up attitude on a 3 degree slope. At 15 ft AGL, raise the nose to 6 degrees and lock it there. Simple.
At 50 ft slowly reduce thrust to be at idle at 30 ft. The reason you can do this on hi-bypass engines is because the N1 fan produces 75% of the thrust, so when the thrust is reduced, the free-wheeling N1 (flywheel) fan continues to produce thrust (at a reducing rate). Not like the old straight jets that would reduce thrust to idle immediately, causing you to fall out of the sky. Watch the AP and copy it.
